The pdf14 LaTeX package

Starting with TeX Live 2010, the various formats that directly generate PDF
default to PDF 1.5. While this allows for more compact documents thanks to
objects compression, it can also lead to compatibility issues with some older
PDF viewers. This package changes back the version of generated PDF to 1.4 with
formats based on pdfTeX or LuaTeX in PDF mode, for documents that need to
achieve maximal compatibility with old viewers.
If you need to generate maximally compatible documents, you may also be
interested in the pdfx package.

pdf14 – Re­store PDF 1.4 to a TeX live 2010 for­mat

Start­ing with TeX Live 2010, the var­i­ous for­mats, that di­rectly
gen­er­ate PDF, de­fault to gen­er­at­ing PDF 1.5. This is
gen­er­ally a good thing, but it can lead to com­pat­i­bil­ity
is­sues with some older PDF view­ers. This pack­age changes the
ver­sion of PDF gen­er­ated with for­mats (based on pdfTeX or LuaTeX
in PDF mode), back to 1.4 for doc­u­ments that need to achieve max­i­mal
com­pat­i­bil­ity with old view­ers.
